HUB LINER.

Application led Ju1y`2, 1926. Serial No. 120,123.

My invention relates to a floating hub liner for use intermediate of the journalboxes and the wheels and more particularly for use intermediate of the journal-boxes and the wheels oflocomotives.

rihe invention has for its object the provision of a liner which may be readily put into place and equally as well removed and replaced when occasion requires without necessity of disturbing or dismantling any of the ruiming gear or adjacent elements of the locomotive; the invention, therefore, obviating the rather laborious and expensive methods at present employed.

The objects and advantages of my invention will all be thoroughly comprehended from the detailed description of the aoco1npanying drawing, wherein- I Figure 1 is a vertical sectional view of one end of a journal and journal-box; a portion of the `journal and wheel being broken away and a part of the liner shown in elevation.

Figure 2 is a vertical sectional view taken substantially on the line 2-2 of Figure 1 looking in the direction of the arrows.

Figure. 3 is a cross-sectional view taken on the line S-Ehof Figure 2. i Y

Figure 4i is a detail perspective view of the non-assembled liner.

In the particular exemplification of the invention, a portion of the journal is indicated at 1() provided with the usual journal-boX shown at 11, while the outer end is provided with'the wheel 12 mounted on the journal in4 accordance with the usual practice in locomotive construction; the journalbox being provided with the lubricating cellar shown at 13. y

Hub liners as heretofore generally constructed and employed have been cast or riveted on the-face of the journal-box, namely intermediate of thel journal-box and the inner side of the hub of the wheel and there fore at inaccessible points. As a result, great diiiiculty is encountered in applying and replacing these liners while the wheels and journaleboxes are in assembled relation. Such constructions involve great time and labor both in application and in renewal; necessitating the placing of the locomotive over a drop pit in order that the wheels and journal-boxes may be lowered, or some means employed for lifting the locomotive oit7 the wheels. Such operations, as is apparent, are quite expensive and require great loss of time and labor.y l

My improved liner is of a construction whichv can be readily and quickly applied Y without disturbing or dismantling any part of the locomotive and therefore without such loss of time as heretofore encountered.

My improved liner provides anwanti-friction bearing face or surface which is in-v tended to fiioat` or be loosely mounted on the journal and therefore free to revolve thereon independently of any other part. The iioating anti-friction liner, which is generally indicated at 14, consists of ya pair of semi-annular complementary members 15 and 16 having.;` tongue and groove relation or connection with each other. That is to say, the section l5, in the particular exemplificas tion, is provided with the transverse or vradial grooves 17,17, while the ends of the section 16 are provided with the Ltransverse tongues 18 which are adapted to lit into the grooves 17. The two sections 15 and 16 when properly assembled Aprovide an annular member having wide bearing faces 19 disposed intermediate of the journal-box 11 and the inner side of the hub of the wheel 12.

The outer perimeter of the sections 15 and 16 are eachprovided with a circumferential groove 2O which is adapted to receive afconstricting band or encircling rod 21.k Gne end of this band orrod is formed in the shape ofahoolr or lug asv shown at 22, see Figure 2, adapted to `fit into a socket 23 formed in section 16; the hook or lug 22 firmly anchoring the `band or rod in place. The bandis preferably formed to t into or be seated in the circumferential groove l 2O ywhen the two sections 15 and16 are as. sembled in matching relation; the band 21 being kof length suiiicient to extend entirely about the two sections and somewhat beyond the socket 23 and therefore with the ends of the band or rod in lapping relation.

The section 16, at a point slightly band or rod (which preferably seats entirelyv within circumferential groove 20) causes the y beyond` the soci-:ct 23, is provided with a radially sectors or liner elements to be tirmly clamped together and that the hook end i2 of the band or rod will also be held in its socket against accident-al removal. On the other hand, removal olf the liner may be readily accomplished by simply unscrewinfor nuts Q5, allowinga the rod or encircling band to be removed, which permits the segmental sections of the liner to be separated; the application of the liner likewise beinfbr easily accomplished without removing or disturbing any of the running gear.

As my improved liner is intended to float about the journal. the sector section 15, atl a pointJ intermediate ot its ends, like the section 16, is also provided with a radially extendingshoulder 2l which is liliewise provided with a groove 2t) therethrough l'or the encircling rod or band '21. As is apparent by havingr both sections substantially identical in general contiguration, they will balancev each other and thus permit the floating action of the liner.

lVith my improved liner, lree to loat-l or revolve about the journal, it is apparent that the entire flat bearinl surfaces are permitted to come into play between the hub of the wheel and the journal-box; and while I have shown the liner composed ot' two sectors or segmental sections, it is apparent that any number may be employed it desired and that changes in other details may be made without, however, departing from the spirit of my invention.

that I claim is:

1. A hub liner comprising a plurality ol flat sided segmental plates arranged in abutting circuml'erenlial relation and adapted to lit about a journal. said plates beingr `Qrooved circumfcrentially on the outer perimeters, an encircling element disposed about. the plates in said groove. at least one olf said plates being provided with a soclteti intersecting said groove and with a radially disposed shoulder 011 each side of said circumferential groove. said socket being adapted to receive one end of the element vwhile the shoulders are adajited to receive the. other end of said element to hohl the same in place.v the relation between the aoelietund shoulders being such that. the ends ol' the element. will lap each other.

2. hub liner comprisiinjr a plurality ot flat sided segmental plates arranged in abutliucY circuinl'erential relation and adapted to lit. about a journal, said plates beinpr grooved circumferentially on the outer perimetcrs. an encircling resilient. clement disposed about. the plates in said groove, at least one of said plates being provided on its perimeter with a radially disposed projection adapted to receive one end of said element and with a socket intersecting said groove adapted to receive the other end ot said element.,

the relation between the projection and socket beiner such thatthe ends ol the element will lap each other. and adjustable means lor securiimr said end olf the element to said projection.

Cl. A hub lirici' comprising a pair ol llat; sided seg-mental plates arranged in abutting -ircumterential relation and adapted to lit about a journal, both plates being j frooved circlnnlerentially on the outer perimeters and each provided on its periphery v-ith a radially disposed shoulder whose outer perimeter tapers toward the periphery of the plate, the radial faces ol' .said shouldersl being diametrically opposite each other in the saine horizontal plane. while the tapered perimetersI ot the shoulders are disposed on opposite sides ol said plane, .said shoulders being f rrooved in alignment with said circ1nnl`erential `L roove, at least; one ot said plates havingr a socket intersecting the circumfercntial groove, a resilient clement encirclingr said plates and seated in said cir cumlerential groove. one end of .said element beingr seated in said socket while the other 1d extends to said shoulder. and adjustable means for clamping` said last end to said shoulder, the relations betnecn the socket and shoulder being such that the ends of said element will lap each other so as to hold the first mentioned end in said socket.

l. A hub liner ot the character described. comprising' a plurality ot' llat sided segmental plates arranged in abutting relation and adapted to lit about a journal, all ol' said plates beingl j i'rooved on the1outer perimelcrs` one ot said plates havingv a radially disposed socket on its outer perimeter and a radially disposed shoulder on its outer perimeter at a point adjacent to the Socket. and an encircling' element adapted to seat in the circumferential groove ol the assembled plates. one end of the element. being' iin-e|'ted in Asaid sof-het while the other end laps the end in the soelitt and is threaded, .said last mentioned end tern'iinatinnr :bove said shoulder and provided with a nut:I threaded thereon.

5. A hub liner ol the character described, comprisinga plurality ol" llat-sided segmental sections. the radial edges oi' the sections having; interloehiucr relation with each other. the eircunii'erential edges bein1 r `rrooved` at least one of said sections havingY radiallyy disposed projection disposed on each .side oiy thi` groove. and u sociicl on its outer perimeter, an einfirclinj, band adapted to lil into said groove, one end ot" the rod b-in;Y of hoolel'orm lo engage in .said socket while the other end is threaded and is disposed between said projections, and means threaded onto the threaded end of the band and engagingr said projections.
